Rated Temperature Reading Accuracy
|
With the logger case sitting in an environmental temperature between 0°C and 50°C: Better than ±1°C for -30°C to +20°C.
Better than ±1.2°C for -45°C to -30°C and +20°C to +40°C.
Better than ±1.7°C for -80°C to -45°C.
Actual performance is typically much better than the rated values. Please see the Rated Absolute Accuracy chart below.
Accuracy figures can be improved by recalibration.

Rated Temperature Reading Resolution
|
Less than 0.1°C for -80°C to 0°C.
Less than 0.2°C for 0°C to +20°C.
Less than 0.5°C for +20°C to +40°C.
Please see the Rated Native Resolution chart below.
LogTag Analyzer® currently displays to one decimal place of °C or °F. The native resolution is what is stored in the LogTag®.
